The "Off if cool" decision is based on the forecast high temperature for the day. Even early in the morning, LawnCheck looks at the forecast high for the day for your zip code. If the forecast high is less than the threshold the cycle will not run. A log will indicate the block, the threshold and the forecast high temperature.

We use forecast high instead of current temperature because in many climates, especially during the spring and fall, the early morning temps can be cool, yet by mid day the temperatures can rise quite rapidly therefore creating a need for some irrigation.
